Russell Simmons said he’s working with Hollywood producers Ron Howard and Brian Grazer on a TV project.

“I am going to buy a TV network,” Mr. Simmons said in an interview during a Tuesday charity event in Hong Kong, adding that he’s working on the project with Hollywood producers Brian Grazer and Ron Howard.

Mr. Simmons, best known as the hip-hop mogul behind Def Jam Recordings, said he hopes to create a network that crosses ethnic lines.

When mainstream networks “say diversity,” he said, “they mean segregation. ‘Let’s do some more black TV.’ Instead, there’s all these cultures that should be more integrated properly.”

Mr. Simmons added: “Instead of giving Paris Hilton a show, for example, you could do one with Amber Rose,” a model who previously dated Kanye West.

“You’d be better off. One is hot, the other is not,” he said. “Networks are a little slow in how mainstream culture is shifting. There’s a lack of integration in Hollywood, and I want to address that.”

It’s not the first time Mr. Simmon has aired his network dreams. In an interview with the New York Post last month, he mentioned his media ambitions, though at the time he didn’t name any co-conspirators.

An announcement confirming the initiative is coming, “hopefully soon,” he said. “Now you’ve heard about it. It’s going to happen.”
